Experienced gardeners are sure that mustard cake can replace all known organic fertilizers.
It turned out that it has another useful property for gardeners. It is not known to everyone.
The list of folk remedies designed to improve the composition of the soil includes mustard cake.
There is even a rumor that it is much better than other known fertilizers. For example, supposedly only 100 g of cake can replace 1 kg of manure.
In fact, this is a myth invented by salesmen. It is difficult to replace rotted manure and compost with another product, especially mustard cake.
But you shouldn't write off the cake. Its benefits are quite significant. Essential oils of mustard repel pests.
In addition, it makes the soil looser. Therefore, it can be safely added during digging in spring or autumn. Take 3 tbsp. per square meter, scatter, and then work with a shovel.
